If there's 1 ♭ in sheet music does that automatically say that the song is in the key of F?

yep, and the flat is "B"

What do you mean?
1 flat sign in the key signature is F major (or d minor ) and the note thats flattened to achieve F (from C major) is B. So F major is FGABbCDEF.

Just cos a song has one flat doesn't necessarily mean it's in the key of F major. It could be G Dorian, A Phrygian, Bb Lydian, C Mixolydian, D minor/Aeolian, E Locrian, D harmonic minor... the list goes on. Any of the modes that are related to F major.

Those are modes. A song isnt in the key of *said mode*. It can be based of *said mode* but ultimately its in a *said key*.

And harmonic minor has a Bb and a C#.

I believe it would also say something like, "Key signature denotes G Dorian."

D Harmonic Minor isn't a key; the key is D minor and still uses one flat in the key signature. (That question was actually my first post in MT.)


And if you're writing modally, you would eaither write your G Dorian piece with two flats and use nat signs by the Es, or write a note that the one flat denotes G Dorian.
